Patented Mar. 25, 1952 UNITED STATES PATENT OFFICE ATTACHMENT FOR HAIR CLIP-PERS Perlcy 0, Clark, Denver, Colo. ApplicationMay 28, 1951, Serial No. 228,702 (01. s 202) Claims. 7 1

This invention relates to motor operated hair clippers, the primary object of the invention being to provide means in the form of an attach.- ment for automatically causing the comb of the clipper to recede during the movement of the clippers over the hair to cut the hair, making it possible for a person unfamiliar with the art of cutting or shingling hair, to cut the hair, the appearance of the hair after having been out being that of a professional hair cut. N

An important object of the invention is to provide supporting means operated and controlled by the movement of the clipper over the head to cause the comb to gradually recede gradually exposing shorter lengths of the teeth of the comb, tapering the cutting of the hair to a close out.

Another object of the invention is to provide a device of this character which maybe readily and easily mounted on the usual motor driven hair clipper without the necessity of making excessive alterations in the clipper construction to mount the attachment.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and poin led out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings,

Figure l is a plan view illustrating an attachment constructed in accordance with the invention, asmounted on a motor driven hair clipper.

Fig. 2 is a fragmental side elevational view thereof.

Fig. 3 is an enlarged bottom view of the clipper portion of the device, equipped with an adjustable comb or guard section.

Fig. 4 is a sectional view taken on line 4-4 of Fig. 3,

Fig. 5 is a sectional view taken on line 5--5 of Fig. 3.

Referring to the drawings in detail, the attachment comprises a main supporting plate 5 which is secured to the rear end of the stationary cutting blade 6, by means of the screws 1 that pass through the spring clips 8, said screws being threaded in openings formed inthe "stationary cutting blade 6, the screws 1 having the double function of securing the supporting plate and said spring clips, to the stationary cutting blade.

Secured to the supporting plate 5, are elongated bearing members 9 in which the rod I0 is secured, the ends of the rod Hi extending substantial distances beyond the edges of the supporting plate 5, as clearly shown by Fig 3 of the drawings.

The reference character ll indicates the comb plate which is "provided with slots [2 that accommodate the forward ends of the bearing members 9. These-bearing members 9 are provided with elongated openings I3 in which the shaft It extends, the shaft I4 being mounted in the elongated bearing 15 formed along the rear edge of the comb plate H. Secured to the comb plate I I, is the U-shaped bar I6 that has bearing members 1! extending therefrom, in which the shaft 14 is mounted, the shaft l4 extending beyond the ends of the U-shaped bar, where they support the wheels I8 that are formed with rubber treads 19 so that the wheels will be rotated as the clippers are moved through the hair, by the frictional contact between the rubber treads and the head over which the clippers are being moved. Thus it will be seen that due to this construction, the comb plate may slide rearwardly and forwardly with respect to the stationary cutting blade, for purposes to be hereinafter more fully described.

As clearly shown by Fig. 2 of the drawings, the wheels l8 are provided with arcuate-shaped eccentrically formedelongated openings 20 providing cam surfaces in which the ends of the rod In extend, the extremities of the rod l0 terminating beyond. the outer surfaces of the wheels [8, where they provide supports for one of the respective ends of the spring members- 2! which spring members have their opposite ends secured to the wheel associated therewith, by means of screws- 22. As the wheels are rotated in one direction, it is obvious that these springs will be placed under tension to return the wheels to their normal positions, when the clippers are lifted from the head. Secured to one of the wheels, is the adjustable stop 23 which is held in position by means of the set screw 25, the stop 23 being provided with a finger at one end, the finger being disposed within the arcuate shaped slot in the wheel on which the stop is mounted, to limit movement of the rod l0, within the slots 20 of the wheels, thereby regulating the movement of the comb bar to adapt the attachment for use in varying the length of the hair out. By adjusting this movement of the comb plate, it is obvious that the hair will be longer at the end of the stroke with the clippers, than it would be if the comb plate should move to the limit of its rearward movement with each stroke of the clipper.

From the foregoing it will be seen that due to the construction shown and described, the clippers equipped with the attachment, may be moved over the head of a person, in such a way that the comb plate of the clipper will gradually recede until the rod I reaches the ends of the slots or arcuate-shaped openings 20, thereby gradually tapering the cutting operation to shingle the hair as is customary when the hair is cut by a professional barber.

It might be further stated that by pushing the U-shaped bar I6 towards the supportingv Plate 5, the comb is raised from the cutting edg'e'of the clippers to permit of ready cleaning and removal of accumulated hair on the clipper.

Having thus described the invention, what is claimed is:

l. A motor driven hair clipper comprising cutting blades, a comb plate slidably mounted adjacent to the cutting blades, said comb plate having comb teeth cooperating with said cutting blades in regulating the length of hair cut, a shaft secured to said comb plate the ends of the shaft providing axles, wheels mounted on the axles, said wheels having arcuate-shaped openings, a rod secured to said clipper with theends of the rod extending within the arcuate-sh'aped openings of the wheels wherebyfrotation of said wheels moves the comb plate rearwardly, exposing said cutter bladesgradually varying the length of the hair out, and spring means for returning said wheels to their original positions.

2. A motor driven hair clipper comprising a clipper head, cutter blades mounted within the clipper head, a supporting plate secured to the bottom of the clipper head, a comb plate slidably mounted on the supporting plate, spring clips secured to the supporting plate and engaging said comb plate holding said comb'plate to the base plate, traction wheels mounted at the ends of said comb plate, said traction wheels having arcuate-shaped openings formed therein, a rod secured to the supporting plate, the ends of the rod being disposed within the arcuate-shaped openings of said wheels, whereby said comb plate is moved with respect to the cutter blades as the wheels rotate, spring members secured to said wheels and having connection with the ends of said rod adapted to return said wheels to their initial positions, and means for regulating rotary movement of said wheels.

3. A motor driven hair clipper, comprising a body portion, a supporting plate mounted on the body portion, a comb plate having teeth, slidably mounted on the supporting plate, the teeth cooperating with the cutting blades in regulating the length of hair cut, means for extending through the comb plate and disposed in said elongated bearing openings, the ends of said shaft extending beyond the ends of the clipper head, spring clips secured to the supporting plate and bearing against said comb plate holding the comb plate in position, traction wheels mounted on the ends of the shaft carried by the comb plate, said traction wheels having arcuate-shaped openings, a rod secured to said supporting plate with the ends thereof disposed within the arcuate-shaped openings whereby rotary movement of the wheels moves said comb plate with respect to the cutting blades of the clipper gradually tapering the hair cut to a close out, as the clipper is moved through the hair, and means for automatically retuming the wheels to their normal positions when the clipper is lifted from the hair being cut.

5. A motor driven hair clipper comprising a body portion having cutting blades, a supporting plate mounted on the clipper, bearing members having elongated bearing openings, secured to the supporting plate, a comb plate'having teeth extending beyond the cutter blades of the clipper, a shaft extending through the elongated bearing openings and being secured to said comb plate, the ends of said shaft providing axles, friction wheels having rubber tread portions, mounted on said axles at the ends of the shaft, said wheels having arcuate-shaped openings formed therein, a rod secured to said supporting plate with its ends disposed within the arcuateshaped openings whereby said comb plate is moved rearwardly as the wheels rotate in one direction thereby exposing greater portions of the cutter blades taper cutting the hair through which the clipper is moved, said wheels being rotated by contact with the head over which the clipper is moved, and spring members connected with the ends of said rod and with said wheels whereby said wheels are rotated and returned to their initial positions when the clipper is moved out of contact with the head being clipped.
